trolyte inlet `6 screw threaded for the inlet tube 7 which has the screw plug S. The two electrodes lO'and 11 are opposed in hori zontally parallel position in said cell Land respectively*comprise the rectangular grids 12 and 13, which are hollow frames oi' cast metal, of greater area at6 the top than at the bottom, open at the top and bottom, and having recessed passageways 14 and 15, for the electrolyte 16, in respectively opposite vertical walls which form the sides of said grids, as shown in Figs. IV and VI. As shown in Fig. II; said grids 12 and 13 have inverted conical sockets 17 and 18 for their respective terminals, and respectively contain active material 2() and 21. Each of said electrodes has a plurality of vertical pas- Sageways, respectlvely 23 and 24, through its active material, and a plurality oi hori- Zonta] openings 26 and 27 through its outer vertical walls, exposing said active material to the electrolyte 16. Said electrodes l() and 11 have soft metal terminals and 3() at respectively opposite ends thereof, l'used in said sockets 17 and 18 and extending through said terminal outlets 4; and 5 in said cover 2; the terminal 3() of the lower electrode extending through the upper elec trode. Said terminals 2S) and 2l() are cast in insulating tubular sleeves 32 and 33, preferably of glass, which respectively incase said terminals as shown in Fig. II; the sleeve '33 of the lower electrode extending through the upper electrode. The terminal .29 of the upper electrode,has the hard metal head35 exterior to said cell l for engagement with a conductor, and the terminal 3U of the lower electrode has the hard metal strap 36 extending, horizontally, exterior'to said cell contiguous with the outer surface thereof, the end of said strap being Spetin the recess 3S of Said cell to prevent its displacement. Y

The plastic medium 3f) seals the jolnt between said cell 1 and cover 3, the joint between said tube 7 and said cover, and the joints between said terminals 29 and 30 and. Asaid cover. The insulating spacing blocks 41, conveniently formed of sheet glass., which resteupon said upper electrode 1() and extend upwardly to said cover 3 at respectively opposite ends of the latter, are confined between said cell 1 -and the respective terminals and normally hold said electrodes in the assembled'position shown in Fig. II.

The separator between said electrodes 10 l' 45, otherwise shaped, andconstructed.-

u qbemade therein without departing from the rubber, which is coextensive with said frame i istry with eachother for `the terminal y of the lower electrode, which extends throiighA the'upper electrode, as shown' in 15.`

and;I 11r comprises Athe'fram'efof insulatin material 43, best shown in Fig. VIII, having recessed passageways at opposite edges thereof for theelectrolyte 16, the corrugated'porous wood panel 46 fitted in said frame, .and the foraminous diaphragm 47 ofV insulating material, for instance, hard 13 and supportedthereby as shown' in Fig. II. Said wood -panel 46and diaphragm 47 Fig.- II.

The. process ofzforming said battery elecv trede 10 consists in providing a grid 12 with the axis ofthe glass tube 33, `butin asseml A the conical terminal socket 17 casting tliesoft i metal -coref29'in the glass tube 32, project-- ing beyond one end thereof, as vshown -in y,Fig. IX, and haring the hard metal head 35 at the other end thereof, and fusing said terminal projection in said' socketlfThe `process of forming the battery electrode 11,

eonsists'in providing the grid 13 with the f conical,terminal-socketlS; casting the soft f' .metal core 30 in the glass tube 33, projecting rat bothends thereof, and fusing ,one of .said terminal projections in said socket.

Thefupper projection of'said core 30, shown inFig. V, is` primarily in alinement with bling the elementsof vthe battery, said projection 'isbentover tlieedge ofthe battery 3 5-cell Il, asshown in Fig. I and electrically f connected,.preferably by solder, with the- I. hardy ymetal @strap 36. are thus differently yconstructed as to-their,`

outer free ends,merely as a matter of con-` venience; for electrical connection with a i specific form of casing, which is not shown,
